Title: Positive two channel can discharge
IPC: B07C5/12
Filed: 1971-12-16
Abstract: 1322099 Rotary conveyers BORDEN Inc 16 Dec 1971 [23 Dec 1970] 58442/71 Heading B8A [Also in Division G4] Cans 14 are tested for leakage in a machine (10) (Fig. 1, not shown), and are transferred to pockets 22 of a conveyer. Each leaking can is ejected from its pocket 22 by a lever 76 at a first station, and discharges on a surface 30. Each servicable can is held by a clamp 85 as the pocket 22 passes the first station, and is released by the clamp 85 at a second station where the can rolls off by gravity on a surface 31. The lever 76 and clamp 85 are mounted on a shaft 74 respective to each pocket 22. The lever 76 is rigid with the shaft 74, while the clamp 85 is freely rotatable thereon. The clamp 85 is urged by a spring 90 bearing on a shaft 88, passing through an oval aperture in the clamp, and secured to the hub 34 of the conveyer. The shaft 74 is rigid with a gear 72. The latter is in mesh with a gear 62 carried by a shaft 68, freely mounted in a bore on the hub 34. Pivotally connected to the gear 62, is an arm 64 on which is mounted a cam follower 60. The latter runs on a cam track 44, which is fixed relative to the hub 34, and has a slight track depression between points B and D (Fig. 5). A cam 50 is pivotally connected to the cam track 44 and is connected to the piston of a pneumatic cylinder 52. Operation.-Detection of a leaking can operates by virtue of escaping gas in a chamber 12 (Fig. 13) developing pressure which is applied to a transducer 146, thereby producing an electrical signal in a solenoid 148. This operates a pin 152 of a memory wheel 150 which at the correct moment activates pressure in the cylinder 52. The cam 50 is raised so as to engage the cam follower 60. This rotates the gear 62 and lifts the reject lever 76 into its eject position (Fig. 6). If the can does not give rise to a reject signal, the cam 50 is not raised, and the follower 60 drops slightly, due to the depression between points B and D. This causes reverse rotation of the lever 76, and a shoulder 75 carried by it, engages a similar shoulder 81 formed on the clamp 85, and rotates the latter clockwise into clamping position against the action of the spring 90 (Fig. 7, not shown). At the point D, the clamp is released, and the can discharges by gravity. There are two identical cam tracks 44 on either side of the hub 34, and alternate gears 72, 62, cam followers 50, cams 50, and cylinders 52, are mounted on opposite sides of the hub, thus enabling double the number of recesses 22 to be provided on the conveyer. This doubles the maximum possible rate of operation.
